Customer Ratings & Reviews

I am pleased with this purchase and would suggest it as a top option for those looking to back up data or use it as an external drive. Speed is excellent and the connection stable. I use this drive for large file storage when editing in Final Cut Pro. I was using Samsung NVMe drives in more generic enclosures however heat became an issue. To date, after I believe two months of constant use heat has not been an issue.

so far - I have had this for 2 months - it has been performing great as a backup for all my major files. and super fast. Almost as fast as the SSD I have installed internally. Super tiny too.

these X9pro SSD's are fast and reliable, and they fit in any laptop bag. They are perfect to work while traveling. Will definitely purchase again.

I own two of these -- amazing for editing professional grade 8k and 4k video connected to Macs. Very fast, very reliable, very small.

BEST SSD ever Small, quiet and holds 4TB. And very fast, I'm going to have to buy another ine!

Light, compact and amazingly fast! Using a pair of them for frog leaping backups. Plug-n-Play, no A/C cord to deal with. Wish I would have upgraded from the old physical drives a long time ago!

This works great and it is tiny! Easy to transport and fast enough to edit video off of on my MacBook Pro.

Absolutely works perfectly for my laptop games it downloaded them at lightning speed and helps them run quite smoothly!

This external SSD is a fantastic combination of size, ample storage space, and transfer speed! I did several speed tests and large media file transfers and I will definitely use this for image and video asset management. Buy it!

The Crucial X9 4 Tb portable drive is so small physically yet so big in terms of the data it holds. I am a photographer who goes on the road for extended periods, so I need a reliable ssd drive to hold my photos. This drive is fantastic and it is the size of a book of matches.

Definitely good transfer speed. Even smaller and lighter than I expected. Easy to throw in my bag everyday.

I use it for DJing to store music. I got 300,000 songs on it loads pretty fast and very compact lightweight and very durable.

Small size and great capacity ... so far so good. This is my first time using a crucial external device and so far no complaints. I literally have over 10,000 images from a recent trip and no problems at all

Fast read and write speed. I have 2 of the same ones and this is my THIRD one! Very reliable and compact! Great product!

I use this as an external game drive for my laptop and it has been amazing for that and will transfer games from my internal SSD in no time flat. It is super small so it's not annoying to toss in your laptop bag to take with you.

It is smaller than I expected. I have a 4TB HDD, that is 64 times bigger in physical size, than this 4TB SSD. It is fast and comes with a USB cable.

Speedy, solid and amazingly tiny. I can carry this in my pocket to my presentations, with all my documents, videos, clips, and presentations easily at hand...with room to spare (both on the disk and in my pocket :))

The Crucial-X9 is the smallest and most compact 4tb solution I have found (be careful not to lose it in the bottom of your bag). Performance is excellent, and it is extremely fast Time Machine backup for your MacBook or large file storage needs.

Fast, compact & economically priced. Prefect for handling large amounts of data such as professional video footage.

Really fast storage in a tiny, sturdy body. Works great as Time Machine backup for a Mac.
